## The panel's verdict

doo is event-registration and ticketing SaaS from Munich-based doo GmbH, and its highest scores are shop and registration (6 to 7) and invoicing and tax (6 to 7): ticket categories, conditional questions, promotion codes and widget or iFrame embedding on any number of websites, a seating tool for events up to roughly 2,250 attendees, and per-category VAT with mixed 0%, 7% and 19% rates printed on invoices doo creates for the organiser. Payments and fees and check-in and on-site score 5 to 6: the on-site module is in beta, recommended for up to 500 attendees and requiring a stable internet connection, and the captured pages give different accounts of refunds — a features page describes automatic repayment while the terms state doo does not process refunds unless expressly agreed. Sovereignty sits at 6 across the bench — EU data centres with EU-only servers on request, ISO/IEC 27001 stated — though data centres are unnamed and no subprocessor list is published. Scores sat close; the widest spread is attendee data ownership, 5 to 7. Pricing transparency trails at 4 to 5.

**Speaks for it:**
- Registration is configurable with ticket categories, conditional tickets tied to questions, promotion codes, add-on products and widget or iFrame embedding on any number of websites
- VAT is set per ticket category, with mixed 0%, 7% and 19% rates possible in one event and the exemption reason printed on bookers' invoices
- doo is the processor under a downloadable Article 28 GDPR agreement, with attendee and booking data exportable as Excel or CSV at any time
- The exit path is unusually explicit: up to 30 days of transition support, at least 30 days to retrieve data after termination, and early-termination compensation capped at the remaining fees
- On-site check-in validates add-on products such as workshops and catering and shows check-in numbers in real time

**Held against it:**
- The captured pages give different accounts of refunds — a features page describes automatic repayment while the terms state doo does not process refunds of ticket prices unless expressly agreed
- The on-site module is in beta, recommended for events up to 500 attendees, and its documented setup requires a stable internet connection
- We found no public information naming the data centres, the subprocessors with their locations, or the company's ownership
- We found no public information on payout timing, chargeback handling or passing service fees on to buyers
- The documented accounting export is Excel or CSV, with no public information on a DATEV export or e-invoice formats such as XRechnung or ZUGFeRD

**Best for:**
- You organise German events that mix VAT rates in one event — 0%, 7% and 19% — and want invoices created on your behalf with your VAT ID on them
- You need a configurable registration flow with ticket categories, conditional questions and promotion codes, embedded by widget or iFrame on any number of your own websites
- You run seated events of up to about 2,250 attendees and want the seating plan to feed badges, check-in and table plans
- You face a data-protection review and need an Article 28 processor agreement, exports at any time, and a stated retrieval window of at least 30 days after termination

**Avoid if:**
- You need on-site check-in for events well beyond 500 attendees — the module is documented for small to medium events with a maximum of 500
- Your check-in stations cannot rely on a stable internet connection — the documented hardware requirements state one is required per station
- Your refund process depends on automatic repayment of ticket prices — the terms state doo does not process refunds of ticket prices unless expressly agreed
- Your accounting hand-off needs more than the documented Excel and CSV exports

## Scores by judge and criterion

Scores out of 5, each judge scoring independently against the published rubric (v1). "n/r" = not rated: the vendor publishes no price, or the judge found no public information on that criterion.

### The judges

- **The Conference Organiser** (v1.0): Runs the annual congress of a trade association: 900 attendees over two days, member and non-member prices, workshops with twenty seats each, and half the bookings made by an assistant for three colleagues at once. Wants the shop on the association's own site, invoices that a company's accounts payable accepts without a phone call, badges printed at the door from the same data, and session check-in that counts towards continuing-education points.
- **The Venue Promoter** (v1.0): Books bands and DJs into a 250-capacity club, four nights a week, and pays the artists their guarantee before the show. Needs the ticket money before the event rather than three weeks after, a fee that buyers pay on top of a twelve-euro ticket, a door app two volunteers can run on their phones without signal in the basement, and the buyers of last month's show on a list the club can mail, not the platform.
- **The Course Provider** (v1.0): Runs a small adult education business: evening courses over eight weeks, weekend workshops for coaches, and a few seminars that employers pay for. Wants registrations with the questions each course needs, a waiting list that fills a cancelled seat by itself, VAT that is right for exempt teaching and taxable workshops in one shop, invoices to employers in her own name, and cancellation rules her terms can point to.
- **The Revenue Accountant** (v1.0): Keeps the books for a concert promoter and two conference organisers and gets a payout statement each month that nets ticket sales, refunds and platform fees into one number. Wants to know who sold the ticket in whose name, which VAT rate applied to each ticket, a fee invoice kept apart from the revenue, credit notes for every refund, and an export that reaches DATEV without a spreadsheet in between.
- **The Data Protection Officer** (v1.0): Advises a federation of sports clubs whose events collect names, employers, dietary needs and the odd wheelchair note. Reads the ticket buyer terms before the feature list, because they say whether the platform is a processor or a controller with its own newsletter. Wants a DPA that names the organiser as controller, subprocessors with their countries, and attendee lists that are deleted after the event instead of kept for marketing.
- **The Skeptic** (v1.0): Has seen "free for free events" turn into a fee on every paid ticket that buyers blame the organiser for, payouts held until a week after the show, and a platform that emails the organiser's audience about a rival's concert. Reads "your data belongs to you" next to buyer accounts on the platform's own app, and an export that stops at names and emails — and asks what leaving would cost.
